This book provides an excellent review and analysis of the latest information on rechargeable Li-S battery research. With a clear and concise writing style and in-depth technical material, this book will appeal to undergraduates and graduates, researchers, chemists, material scientists, and physicists working in the field of energy storage, especially those with an interest in Li-S battery technology. IEEE Electrical InsulationMagazine shows lithium-sulfur (Li-S) batteries give us an alternative to the more prevalent lithium-ion (Li-ion) versions and are known for their observed high-energy densities. Systems using Li-S batteries are in the early stages of development, and commercialization however could potentially provide higher, safer levels of energy at significantly lower cost. In this book, the history, scientific background, challenges, and future perspectives of the lithium-sulfur system are presented by experts in the field. Focus is on past and recent advances of each cell compartment responsible for the performance of the Li-S battery and includes analysis of characterization tools, new designs, and computational modeling. As a comprehensive review of the current state of play, it is ideal for undergraduates, graduate students, researchers, physicists, chemists, and materials scientists interested in energy storage, material science, and electrochemistry.
